How To Fix A Leak In The Rear Right Brake Drum Of 1990 Suburban 4x4 Half Ton?

It's either brake fluid or gear oil,if its brake fluid its probably a wheel cylinder leaking--those are cheap and not a big job to install,I paid like $10 for one for my truck and was able to sneak it in without pulling off the brake shoes..
If it is gear oil,its a lot more work--the seal thats leaking cant be replaced until you pull the axle out,that requires taking the rear diff cover off,and taking out the lock screw in the spider gear pin so you can push in on the axle and get the C clip off the end of the axle shaft..
This can be a real pain,because that lock screw likes to snap off at the head,and its a major nutcracker to remove the remains of it once that happens..but if it comes out intact,the whole job only takes an hour or so..you'll need about 3 quarts of gear oil to refill the diff..
Sometimes the axle seal leaks due to the wheel bearing getting worn and it made a grooved area on the axle where the roller bearings ride against it..there are two ways to fix that--new or good used axle shaft,or a "repair bearing" they sell,that moves the area of contact to a un-worn spot on the axle...some do not like that idea because the scoring on the axle does weaken it some and could lead to it breaking..
If it is gear oil,its a lot more work--the seal thats leaking cant be replaced until you pull the axle out,that requires taking the rear diff cover off,and taking out the lock screw in the spider gear pin so you can push in on the axle and get the C clip off the end of the axle shaft..

Oil, brake fluid, or dog urine? Identity is crucial.
I once pulled the dual wheels, brake drum, and backing plate off my old CJ5 looking for a leak that had stained the concrete of my driveway.
Only to discover that my dog had peed on the wheels washing some mud off onto the concrete.........

....bet you were pissed when you found out it WAS piss!..Might be time for a "taste test"...gear oil,brake fluid,and dog piss all have their own distinctive flavor..

Found the leak coming from behind the right rear brake drum.
The emergency brake is all the way up the the console and the vehicle will not move
Maybe I'm misunderstanding, but isn't that what it's supposed to do? The e-brake is a mechanical connection, so fluid is irrelevant to how it functions. Pull off the drum to be sure if you can't differentiate between gear oil/brake fluid by smell or appearance-regardless of which is the issue, you'll have to do it anyways for repair.

Wish I could like more than once.
Ah, okay. For some reason I thought the ebrake was applied. You've got some other problems than wheel cylinders or leaking axle seals. You'll want to check your ebrake mechanism and cable for binding and proper installation. Has the vehicle not been driven in a while? That's usually the main cause of frozen brakes. Get those drums off and figure out what you're working with.

If you know you are losing fluid, and a previously-working e-brake can't go down, AND the vehicle is incapable of moving, it sounds like oil has caused your brake shoes to swell. Usually it just makes the brakes grab very agressively, but if they are drenched long enough they will become slightly larger. If they were sufficiently swollen, the E-brake would not be able to budge them (because they were already tight) and you would also have that drum bound tightly (keeping the vehicle from reasonably moving).
How much oil is seeping out of the drum? It doesn't take much to screw with the shoes.
Hadn't thought about that. Try to adjust the shoes in. If it starts turning, that's your culprit.

Some was two days ago but not much today.
Plus there is break pressure on the (regular)break pedel
Take it apart and look. Gear oil is much different than brake fluid. And you've got a fairly large brake reservoir, if the leak isn't huge, it would go awhile before you'd get low and lose pedal.
Leak needs to be fixed before anything else, any oil on the shoe and the shoe is garbage, so regardless if e-brake is a problem or not, the leak is for sure.
Wheel cylinder or axle seal are pretty easy repairs all things considered, assuming rust doesn't hamper certain parts of disassembly...

To adjust rear shoes turn the star wheel adjuster at the bottom where the shoes come together.
